The water heats to 112 degrees slowly when feet are in it ... can't set it to heat the water and put your feet in later... vibrates a little, bubbles a little

I work on my feet. Sometimes 8 hours. Sometimes 10. I'm always moving around and my body sometimes lets me know it's time to stop. This thing is great. There is nothing like coming home from work and just putting your feet in for a good soak. The heating element packs a punch so start low and work your way up because the water gets HOT! The jets are great too. You'll love this thing.

For some reason I thought the rollers automatically rolled. They do not. But other than that the product it works as I expected.

I am shocked how well this footbath heats the water. I am so used to placing scalding hot water in a foot bath. I let my 5 y.o. try it first and you know little ones don't like water on the warmer end. (It read 95 degrees.) Without even adding more hot water it had increased the temperature quickly. I have noticed that it drops several degrees below set temperature, but the heating works so well I could care less. I have literally had it in the house for 30 minutes.
The bubbles are weak. (Completely expected) and they one come out in the arch area. On the top of product (see picture) it tells you to turn on bubbles to improve heating. (Assuming to circulate water)
There is a vibration too which is gentle, but it is nice. The rollers in the footed are ok. I believe they are triangular in shape.
I really like that there is a small compartment to place bath salts and cover it.(Assuming in to keep big particles out of heater and bubbler.) It is really nice because many foot baths with heat tell you not to use anything but water in the footbath.
If you are realistic and want a foot bath that actually keeps water warm (Let alone hot and can make hot water) this foot bath is for you. The price was very reasonable.
I will try and come back and update after a month or so to update.

As others have said, the vibration and bubbles aren't very substantial. But most people said the heat was ok so that's why I purchased it. It will heat water, maybe about 10 degrees every 3-4 minutes, which is pretty good. But I dislike that it doesn't "hold" the temperature once it reaches the desired level. Instead the LED light for the heat just turns off and it starts cooling down, so you will need to press the heat button every few minutes after it reaches your initial setting in order to have it maintain the desired temperature. This is a little annoying and I wish I knew that before I purchased it.

First Update: After more testing the heat will stay on, but the temperature swing is higher than I would like. When set at 110º it will go all the way down to 106º before it starts heating again.

Second Update: The manufacturer contacted me after my review, expressed their concern, and offered me a full refund. They did not ask me to remove or change my review which I respect them for.

Overall it seems like a good product for the price point and it is probably better than the competitors.
